This book was released on 2012 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Symposium "Science and the Challenge of Managing Small Pelagic Fisheries on Shared Stocks in Northwest Africa" took place in Casablanca, Morocco, from 11 to 14 March 2008. It was attended by around 100 participants. Forty-three oral presentations and 30 posters were presented. The Symposium was split into four main sessions: resources and exploitation-biology and ecology of main resources and status of fisheries; dynamics and variability of pelagic fish populations and environmental influences; methods and models for assessing small pelagic fish stocks; and management of fisheries on shared resources. The Symposium ended with a general discussion aiming to identify specific problems to address as well as providing recommendations on ways forward. These Proceedings present a summary of the various sessions as well as on the outcomes of the discussion. They also provide scientifically reviewed papers and many of the papers in support of posters presented at the Symposium (non-scientifically reviewed). The papers and posters are available at www.smallpelagics2008.org ."--Page v.

Meeting and published by Food & Agriculture Org.. This book was released on 2006 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fifth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Nouadhibou, Mauritania, from 26 April to 5 May 2005. The meeting continued to focus on data quality and on the analysis of trends in the basic data (landings, catch, effort, abundance, length and age distribution) and trends in the fishery independent survey data. The structure of the report is the same as that of the previous Working Group report (FAO, 2004), with the addition of two chapters, one on bonga (Ethmalosa fimbriata) and one on anchovy (Engraulis encrasicolus). A separate section is devoted to each of the main groups of species (sardine, sardinella, horse mackerel, chub mackerel, bonga and anchovy). For each of these, standardised information is given on stock identity, fisheries, abundance indices, sampling, biological data, assessment, management recommendations and future research. In the absence of reliable length and/or age compositions, the Working Group used production models for all stocks. The results of the assessments indicate that the sardine stock in Zone C is not fully exploited and the Working Group hence noted that the total catch level may be temporarily increased but should be adjusted to natural changes in the stock. A constant monitoring of the stock abundance and structure, by scientific surveys, independent from catch data, should be ensured, to detect unanticipated changes that may require urgent management measures. As regards the central stock of sardine (Zones A+ B), it is recommended not to increase catches above the average level of the last five years (600 000 tonnes). The stock of round sardinella was found to be fully exploited and it was hence recommended not to increase catches of sardinella above the current level of 400 000 tonnes (2004). As a precautionary approach, the Working Group recommended not to increase catches above the average level of the last five years for the horse mackerels (80 000 tonnes for Trachurus trachurus and 170 000 tonnes for T. trecae) and not to increase catches above the 2004 level for chub mackerel (220 000 tonnes). For bonga the Working Group recommended as a precautionary measure that the catch level should not exceed the average over the last five years (42 000 tonnes) and for anchovy the catch level should not exceed the average over the last three years (160 000 tonnes). In formulating the results of the assessments, the Working Group noted that it lacked a set of uniform reference points and management objectives for all stocks in the area. The Group noted that the selection of appropriate reference points required more time than was available during the meeting. It was therefore decided that some members will look further into this problem, working by correspondence, and present a working paper at the 2006 meeting. At that meeting the Working Group will attempt to agree on a common policy concerning the way it presents its management advice for the various stocks.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le long des côtes nord-ouest africaines, parmi les plus poissonneuses au monde, les ressources halieutiques sont importantes tant du point de vue socio-économique que culturel. Les petits poissons pélagiques sont suivis au niveau sous régional depuis plus de trois décennies en s'appuyant sur les méthodes hydroacoustiques d'évaluation de stocks. Ces campagnes ont ainsi permis de fournir aux gouvernants une base scientifique en matière de prise de décision à des fins d'aménagement des pêcheries pélagiques. Un défi spécifique est de connaitre leur représentativité par rapport aux stocks ciblés. Nous rassurons sur cette représentativité sur la couverture de Sardinella aurita par ces campagnes. Par contre, pour S. maderensis une partie du stock ne serait pas échantillonnée et la méthode n'est pas adaptée pour Illisha africana et Ethmalosa fimbriata. Nous reportons des déplacements vers le nord dans la répartition de S. aurita et d'autres espèces de pélagique, attribués à la redistribution de l'intensité et de la productivité des upwellings [découpé en 5 sous zones du sud Maroc au sud Sénégal], diminuant ainsi l'abondance de la sardinelle dans la région côtière intertropicale. Pour la première fois en utilisant des séries chronologiques d'observation indépendantes à la méso-échelle, nous montrons un changement vers le nord dans la distribution de S. aurita depuis 1995 et l'attribuons au fort réchauffement de l'océan dans la région. De plus les changements spatiaux observés dans la biomasse de S. aurita au cours des 20 dernières années sont du même ordre de grandeur que ceux enregistrés pour les isothermes de surface. De tels changements auront une incidence sur les considérations politiques dans la gestion de la sécurité alimentaire dans plusieurs pays d'Afrique de l'Ouest.

This book was released on 2005 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans la région nord ouest africaine considérée (Sénégal, Mauritanie et Sahara occidental), les petits pélagiques représentent, sur le plan quantitatif les principales ressources halieutiques. Une forte hétérogénéité et une grande variabilité aussi bien saisonnière qu'inter-annuelle sont observées tant au n iveau des biomasses que des captures. Pour mieux comprendre les variations qui affectent ces espèces, nous focalisons l'attention sur Sardinella aurita (sardinelle ronde) et Trachrus trecae (chinchard noir africain) en zone mauritanienne. Ces deux espèces sont considérées comme un exemple de la variabilité des autres espèces de petits pélagiques. Après avoir dressé un panorama des déterminants de cette dynamique à travers une étude bibliographique détaillée, les données des campagnes plactonichtyologiques menées dans la zone mauritanienne de 1997 à 2001 ainsi que 30 années de données de campagnes acoustiques réalisées dans toutes la sous-région sont analyses, afin de caractériser la distribution spatio-temporelle de ces espèces. Pour la période commune, une intéressante corrélation inter-annuelle entre ces deux indices est ainsi mise en évidence pour les deux espèces avec un décalage d'une année dans le cas du chinchard noir africain. Il apparaît aussi que la dérive au large des larves n'est pas synonyme de l'échec du recrutement. Une nouvelle zone de reproduction de ces deux espèces serait identifiée pour la première fois dans le cas de la sardinelle ronde au sud de la ZEE de la Mauritanie à proximité des nouveaux champs pétrolifères offshore. A la lumière de l'analyse des zones de reproduction et les structures démographiques issues des campagnes acoustiques pour Sardinella aurita, l'hypothèse de deux stocks semble se confirmer.
